used in laundries and cleaning establishments, wherein a horizontally disposed perforated cylinder, split longitudinally and axially into upper and lower hingedly connected halves, operates in conjunction with upper and lower housings, movable vertically to enclose and uncover the upper and lower halves forming the cylinder, which actuate mechanism, during such movements, to automatically invert the upper half of the cylinder to a loading position to receive the load for the next cleansing and to automatically move the lower half of said cylinder to a dumping position and to automatically return said lower half to a receiving position and the upper half, with its replenished load, to normal matching position with the lower half to form said cylinder, thereby dumping the load from the upper half into the 20 lower half.

The primary object of the present invention is to provide a new and improved automatic loading and dumping washer to save the time and labor required for manual loading and unloading.

Another object is to provide a new and improved washer having improved means actuated by the opening and closing of a stationary housing, usually enclosing the rotatable cylindrical perforated washer, for automatically inverting 30 the top or lid of said cylinder to aloading or receiving position upon one side of the device and for automatically moving the bottom half or container to a dumping position upon the opposite side of the device, thereby permitting the loading and unloading operations to take place substantially simultaneously to eiiect a further saving of time. Y

A further object of the invention is to provide new and improved means for positively locking the two halves of the rotatable cylindertogether to prevent their opening or separation during the washing or cleansing period.

A still further object is to provide actuating means for inverting the lid, or upperhalf of the cylinder, to receiving or loading position and reverse, and the lower half to dumping or dispensing position and reverse, by means of mechanism which normally disengages said upper and lower halves and automatically engages said halves to operate the same and automatically disengages said halves after the operation, whereby said rotating cylinder may be free to rotate when said housing is'closed and the moving mechanism automatically disengaged.

5 A still further'object is to provide means for normally positioning the upper and lower halves to facilitate engaging relation of the operating mechanism therewith, when the rotating impulse has been removed from said rotating cylinder.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present specification, and in which- Fig. 1 is a broken side elevation, disclosing my improved washer, the central vertical lines being used to indicate that the said washer may be of any suitable length;

Fig. 2 is an enlarged broken transverse sectional view taken on line 2-2 in Figs. 1 and 3 of the drawings in the direction indicated;

Fig. 3 is an enlarged broken View, partly in section, taken on line 33 of Fig. 2 of the drawings, disclosing one end of the perforated cylindrical washer in elevation and one end of the outer housing in section, and also disclosing the parts in normal position to permit rotation of said washer;

Fig. 4 is a slightly reduced transverse sectional view disclosingthe initial or first movement of the device;

Fig. 5 is a similar view disclosing the dumping and receiving positions; and

Fig. 6 is a detail view disclosing, in plan, the cradle which supports the cylindrical, rotating washer.

Referring to the drawings:

The numeral l is used to designate in general a suitable frame within which are rotatably mounted and supported the trunnions 2 mounted upon the upper surfaces of the opposite ends of an open rectangular cradle 3, said cradle being below the axis of the trunnions 2 so that the cradle 3 is rotatably suspended, the purpose of which will hereinafter be more fully set forth. One trunnion is provided with the usual triplicate pulleys 4 for rotating the cradle in opposite directions, according to present custom, while the other trunnion 2 is provided with a wheel 6 havingan aperture 1 which registers with a similar aperture 8 within a bracket 9, mounted upon the frame I, to receive a pin or other suitable device "H to retain the cradle 3 in stationary suspended position during the loading and dumping operations, as disclosed in Fig. 1 of the drawings.

The perforated cylinder or washer comprises what I designate throughout the specification and claims, for simplicity, a lower half l 2 having one edge hingedly connected as at IE to one side of the cradle 3 and its free edge resting upon the opposite side of said cradle, and an upper half l4 having one edge hingedly connected to said opposite side of the cradle 3 as at I1 and its free edge resting upon the first side of said cradle 3, the two halves thus being in matching relation to form a cylindrical washer, as disclosed in Fig. 2 of the drawings.

The two halves l2 and [4 are held locked in matching relation, during their period of rotation, by means of a latch l8 pivotally mounted upon the under side-of the cradle 3 upon which the hinge I6 of the lower half I2 is located. gThis latch is preferably in the form of an inverted U y and extends the length of the said halves and rests upon the flange or free edge of the upper half M. A rod i9 connects the latch [8 to an arm 2| pivotally mounted upon one end of the cradle 3 and provided with a slot 22. When the arm 2| is lowered, it closes the latch [8 upon the upper half l4 and thereby locks the upper and lower halves l4 and i2 respectively, together,- and to the cradle 3. The tension of a spring 23, connected to the cradle 3 and the arm 2|, normally retains the latch IS in locked or unlocked positin-by ;holding the connecting point of said rod with said arm on either side of the pivotal center of said arm, in thewell known manner.

' While I have illustrated, in detail, only one end of the washer and its component operating mechanisms, it is to be understood that similar mechanism is applied to both ends of the device, the parts being right and left, and may be described as follows:

. While the upper and lower halves l4 and I2 extend fully from side to side of the cradle 3, they do not extend entirely to the ends of said cradle,

but stop short of said ends,.as indicated in dotted lines in 'Fig. 6 of the drawings, in order to proyide a space between the ends of s aidupper and lower halves and the inside of the cradle 3 to permit the passage and operation of certain mechanisms. I w v A rigid arm 26 extends downwardly from each end of the upper half I4, beyond the end of the cradle 3, and to a point preferably below the center of the lower half l2 and has a slot 27 arranged on a line slanting approximately 45 degrees from the hinge I! of the upper half 14, as disclosed in Fig.2 of the drawings; I

A lever 28 is pivotally mounted upon the cradle 3 concentric with the hinge H of the upper half I4, one lower end of said lever substantially registering with the slot 21 of the arm 26, although the twolhave no connection. A suitable link 29 connects the free end of said lever 28 withthe top edge of the lower half l2. The opposite end of thelever 28 is slightly bent for a purpose herein- ;after more fully set forth, and is provided with a .On the inner side of each end of said upper housing 33;is a link 43 pivotally suspended from a sleeve 44 slidable upon a square shaft 46 rigidly secured to said upper housing 33. The lower ,end of the link 43 is provided with a pin 41 arranged to engagethe slot 21 of the rigid arm 26 secured to the upper half l4, But the pin 41 is normally prevented fromengaging said slot, while .the. HD1 61 housing ,33iselowered to enclose the after described.

- 33 ,are beyond the path of rotation with the re the pin H is placed through the aperture 8 of I The motor 4| is started, which upper half M, by means of a spring 48 interposed between the inner top of said upper housing 33 and the top of the sleeve 44, the tension of which spring also normally retains said pin 41 between a pair of keepers 49, rigidly mounted upon a lower housing 51, which keep the pin directly opposite the slot 21 of the arm 26, as disclosed in Fig. 2 of the drawings. A spring 5| normally holds thelink 43 substantially vertical by pulling it against a flat limiting stop 52, shown in Figs. 3, 4, and 5 of the drawings, but removed from Fig. 2 with the end of the upper housing nearest the observer, as it would other wise cover other parts and tend to confuse the said Fig. 2. The link 43 is free to slide vertically over this stop 52 without changing its vertical position. r

A pin 56 projects inwardly from the bottom edgeofeach end of the upper housing 33to engage the slot 22 of the locking -arm'2|, actuate the same to unlock and then disengage it, when moving to uncover the upper half i4, and to "perform the reverse to lock" and disengage it during a closing or covering movement of the said upper housing 33. v

A lower housing 5'4 is also mounted for vertical movement to enclose and. uncover the lower half l2 by means of suitable worms 58, driven through bevel gears 59, shaft 6 spur gear 32 and pinion 63 of a suitable motor 64. The lower one side thereof to engage a pair of pins 3?, one

on each end of the upper half Hi, When the same is moved to semi-loading position herein- In operation: v v V v The parts, during the washing or cleansing period, are in theposition disclosed in Figs. 1, 2, and 3 of thedrawings. That is to say, the upper and lower halves I4 and i2 are locked by the latch |8 in matching relation to form a cylinder and-are enclosedfby the upper and lower housings 33 and 51 respectively The lower housing is adapted to containga cleansing solution H, as disclosed in Fig. 5 only. As the upper and lower halves are rotated by the cradle 3, trunnions 2, and pulleys 4 in the well known manner,-the pins 41 and 5'6 of the upper housing spective parts they later engage and actuate.

When the washing period is completed and the rotative powennot shown, is disconnected .from the trunnion 2 of the cradle 3, the said.

cradle will normally come to rest with the sev- 5 5 eral parts in their proper receptive positions by reason of the fact that the supporting cradle 3 is suspended belowthe axis of its trunnions 2 and the weight of the rigid arms 25,- the levers 28 and links 29, all extending below theaxis of said trunnions 2, further tend to bring the matching upper and lower halves I4 and I2 and their levers and arms into the proper horizontal position to be engaged. When this positionis attained,

position.

rotates the worms 34 and raises the upper housing 33 to ;.uncover..the"uppervhalf I4 of the cylindrical 'washer. The first or initial portion of this upward movement first moves. the pin.5S into the slot 22 of the arm 2| (see Fig. 2 of the drawings) and after engaging said slot moves said arm to release the latch Hi from the free edge of the .upper half M. The pin 41 of the link 43 is prevented from engaging the slot 21 in the lower end of the rigid arm 25 attached to the upper half 14, by the tension of the spring 48 on the sleeve 44 from which the link 43 is suspended, .until the pin 56 has actuated the arm 2| .to release or unlock the latch l8 and thereby release the free edge of the upper half l4. After the pin 56 has disengaged the slot 22 of the arm 2| in its continued upward movement, and when the sleeve 44 reaches its lowermost position on the square rod 46, the pin 4? will be moved from between the keepers 49 and into the vertical slot 21 on the lower end of the rigid arm 26 attached to the upper half I4, as disclosed in dotted lines in Fig. 2 of the drawings. The upper housing 33 then continues to move upwardly and by means of the pin 41 moves the upper half [4 of the cylindrical washer to what I term a semi-loading or upright position, with the pins 51 of the said upper half 14 resting against the supporting earns 66 of the lowerhousing, as disclosed in Fig. 4 of the drawings. The upward movement of the housing 33 is stopped at this point by means of any suitable mechanism, not

shown, as it forms no part ofthe present invention and is subject to unlimited variation.

The motor 64 is now started, which lowers the lower housing 51 to uncover the lower half l2 of the washer. As the lower housing 51 moves downwardly, the grooved supporting cams 65 move downwardly also, and the grooves 9| thereof engage the pins 61 and lower the upper half I 4 until it engages the flange 3! of the lever 28 when said lever will be moved and through its connecting link 29 move the lower half l2 of the washer to a dumping position, as disclosed in Fig. 5 of the drawings. Any suitable truck 12 with a suitable apron 13 may be in readiness to receive the load thus automatically dumped from the lower half [2. At the same time a new load may be placed within the upper half l4 which has been inverted or moved to a loading position. When the new load has been placed within the upper half, while inthe loading position, the motor 64 is reversed, which will return the lower half [2 to normal position, and the lower housing to enclose said lower half 12. But it should be noted that the lower half I2 is fully restored to its matching or normal position before the .upper half I4 is fully returnedto semi-loading position. The purposev of this is to have the lower half l2 in receiving position before the upper half l4 actually dumps its new load into the waiting lower half [2.

When the upper half [4 is nearing its semiloading position, the now horizontal slot 21 in the free end ofthe rigid arm 26 will engage the pin 41, but if said pin should not accurately register with the slot 21, the lower end of the link closed upon the lower half 12, at which time the pin 41 of the link 43 will continue to move downwardly and out of the now vertical slot 21 and into the space between the keepers 49. Continued downward movement of the upper housing 33 will cause the pin 56 to enter the slot 22 of the now upwardly extending or unlocked locking mechanism and move the same to lock the latch l8 and secure the upper and lower halves l4 and I2 into matching relation to form the cylinder.

As the pins 56 and 41 have disengaged their respective slots, the cradle 3 with its upper and lower halves is free to rotate and wash in the usual manner.
